“…Moreover, studies by Clain et al (2004) and Gousset et al (2005) have also shown that some wild species such as S. torvum have high levels of resistance to pests, nematodes and pathogens (Collonnier et al, 2003;Clain et al, 2004;Gousset et al, 2005). This suggests the potential to introgress stress resistance genes into cultivated eggplants to enhance their resistance to pests and diseases.…”

Wild relatives of eggplants represent a good source of variation for breeding programmes, in particular for traits related to biotic and abiotic stresses and also fruit quality traits. However, wild species remain largely unexploited for eggplant breeding compared to other crops like tomato. Seven cultivated eggplant accessions (SM001-02, SM001-04, SM001-06, SM001-07, SA002-02, SA002-03 and SMA003-03) were crossed with three wild accessions (ST004-03 (Solanum tovum), San005-01 (Solanum anguivi) and SA002-08 (Solanum aethiopicum)) in an open field using completely randomized design. The success of fruit and seed set as well as seed germination depended on the cross combination and the direction of the cross. In this regard, no fruit set was recorded when the wild accessions were used as female parents. The highest fruit set and mean number of seeds/fruit was obtained from the crosses Sm001-07 × ST004-03 (6%; 264 seeds) and Sm001-07 × San005-01 (5.7%, 114 seeds), respectively. The germination of hybrid seeds was recorded in only three crosses, SM001-07 × ST004-03, SM001-07 × San005-01 and SA002-02 × San005-01 with germination range from 3.3 to 16.6%. However, plantlets from these seeds did not survive after two weeks of germination. The hybridity of the putative interspecific F1 hybrids (through tissue culture) was confirmed with a morphological marker. These hybrids obtained will contribute to broadening the genetic background of cultivated eggplant species used in this study and to the genetic enhancement of this crop.

“…It has desirable traits such as disease resistance, which may be transferred by introgression into the eggplant genome (Singh et al, 2006;Baysal et al, 2010). Several studies have shown that S. torvum has high levels of resistance towards pests, nematodes and pathogens (Collonnier et al, 2003;Clain et al, 2004;Gousset et al, 2005). It has been used as a rootstock for the grafting of susceptible tomato and eggplant varieties (Peregrine and Ahmad, 1982;Singh and Gopalakrishnan, 1997).…”

ABSTRACT.Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed to be true interspecific hybrids. Eighteen and 14 bands from 7 RAPD and 14 ISSR primers, respectively, were polymorphic and present in all five hybrid seedlings and their parents. The morphological characteristics of leaf margin, inflorescence type and spine positions of the five seedlings were intermediate to the parents. These interspecific hybrids had low pollen viability, probably due to abnormal meiosis.

“…Bacterial wilt may cause up to 100% yield loss in Solanum melongena (eggplant) or Solanum lycopersicum (tomato). Nevertheless, tolerance to R. solanacearum exists in Solanum torvum [4,5], a wild species native to India and closely related to eggplant [6]. This species, widely distributed in tropical and subtropical areas such as in the Ré union Island (France), constitutes a diploid model for studying disease-resistance genes in the Solanum genus.…”
